Needed to go fill up the truck, which is a FFV.At my closest station RUG was $2.53.9 and E85 was $1.45.9.With the $1.08 price differential, the 12% hit in mileage is worth it. So, I went E85.Out of curiosity, for those of you with FFV's,at what price differential to you decide to burn E85 instead of RUG?

The MPG difference is generally 27%. It's only lower, say as low as 16%, when the ethanol content is reduced to 50%, such as during the winter. Remember, ethanol content is reduced in winter to ensure engine starting.

The MPG reduction is directly proportional to the ethanol content. Even in South Florida, ethanol content is often reduced in the winter.

I use it for the fact that it burns cleaner, which in turn keeps the combustion chamber cleaner not to mention the higher octane rating. Some will say it is all in my head but when I run it I can tell a difference in better throttle response and power.

I don't buy on price differential alone, though I might in the future.

The truck just seems to run better on the corn juice.

So, if I am paying only 10% less than RUG, perhaps that isn't the right comparison. E85 is over $1.00/gallon cheaper than premium, which still doesn't have the octane of E85...so, at 10% cheaper, with a 20% MPG hit (based on tracking truck performance, not BTU comparison) I still prefer E85, for the performance.

I saw where it is down to $1.25 a gallon in Indiana.

The truck runs well on it, although I rarely buy it.The one time that I started with basically an empty tank and filled it up with E85, I got 17.5 MPG vs. 20 w/RUG. However, for over a buck a gallon cheaper, I figure I'm not any worse off.At least until RUG goes down.

I'm with you on the performance.I feel if I take the mileage hit, that I need to make up for it on price.I figure I can lose 12% on mileage, if I'm paying 43% less for it.

If corn juice wasn't subsidized by all of us, then it wouldn't even exist in a capitalistic system as it is a carbon negative fuel source and we're burning our food source in our gas tanks. It takes diesel to plant, cultivate and harvest the 1 ear of corn that the 7 foot tall stalk produces, ammonia nitrate (natural gas) to fertilize it, and energy to cook the enzymes into alky you burn in your tank...so just say no and decrease the demand for it.
